I knew the bag was big from talking to other owners of the bag and checking it out myself, but for some reason it feels BIGGER once you get it in YOUR hands. Not sure if it was me or a flaw in my particular bag, but I had a very hard time getting the snaps for the shelves to snap (no one else I talked to who owns it had that issue). That being said, I do like the double support of the snap AND the velcro for the shelves.
